Solved: How to see versions mac

Seeing the version of MacOS you are currently using is vital for ensuring your applications are running correctly and for troubleshooting issues. Whether you are a tech-savvy professional or a casual user, this version information can be crucial. Furthermore, such knowledge can help you keep your system up-to-date by downloading the appropriate updates for your current MacOS version.

How to Check the MacOS Version

Checking the MacOS version can be accomplished in just a few simple steps. On your desktop, click on the Apple icon in the top left-hand corner of the screen. This will prompt a dropdown menu where you will need to select ‘About This Mac’. A window will then appear displaying the current MacOS version you are using.

Java Code to Check MacOS Version

For developers needing to programmatically determine the operating system version, we can use Java’s system property feature to accomplish this. Here’s a standalone Java application which will achieve this.

public class Main {

    public static void main(String[] args) {

        String os = System.getProperty("");
        String version = System.getProperty("os.version");
        System.out.println("OS: " + os);
        System.out.println("Version: " + version);

In the main method, we are obtaining the operating system name and version by querying the system properties with keys “” and “os.version” respectively. The results are then printed to the console.

  • System.getProperty(“”): This function call retrieves the name of the operating system.
  • System.getProperty(“os.version”): This function call retrieves the version of the operating system.

Importance of MacOS Versions in Development

Knowing the operating system version is critical in software development for a multitude of reasons. Apart from ensuring that the software you develop is compatible with the user’s version of MacOS, it’s essential for troubleshooting bugs and issues, which may be prevalent only on certain versions.

Furthermore, the features available in a specific MacOS version determines how your application can interact with the system. Hence, as a developer, understanding these nuances can facilitate a smoother, more enjoyable user experience.

Over the years, Apple has consistently introduced new features and performance improvements in each successive MacOS release. Therefore, it’s important to optimize your applications to make use of these advancements where possible.

In conclusion, understanding your MacOS version can be instrumental for a wide array of tasks. Through the intuitive graphical interface or with a simple Java program, you can easily determine the MacOS version and optimize your interaction with your system or aid your development process.
